HEARING-SHOE FOR COUPLING-YOICES.

Application filed December 19, 1913.

T all whom it may concern:

' Be it known that l, l'VAL'ii-ln E. COFFIN, a citizen of the United States, residing at Cleveland, Cuyahoga county, Ohio, have mvented a new and useful Wearing-Shoe for Coupler-Yokes, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is an elevation of a coupler yoke showing my invention applied thereto; Fig. 2 is a bottom view showing one of the wearing shoes partly in sectionfl ig. 3 is a section of the yoke and one of theshoes; Fig. l shows a modified construction in which theyoke is supported on a single tie plate, and Fig. 5 shows a bottom plan thereof.

My invention relates to coupler yolre' andconsists in inter-posing a wearing plate' or shoe between the yoke and the yoke supporting mechanism to prevent wear of the yoke. v

When coupler yokes are supported by tie plates or similar supporting devices the lower horizontal arm of the yoke bears upon such device. The surface of the yo'kearm in contact with the supporting device .is, relatively small, and as the yoke and the parts it carries are heavy and] are in frequent motion relati e to the supporting dc-L vice rapid wear occurs at the point of con tact which may render the yoke in a com paratively short time unfit. for furthensery; ice. By the employment 'of myanvntioii the wear is transferred from the yoke to the wear plate, which can be readily reworn;-

Referring to the drawings, Ac indicates the yokeg- Bthe wearing shoe or plate and C the yoke supporting device, here illustrated in the form of tie plates, whiciifin e attached to the draft sills l). 'ilheflyekerbhas the usual reinforcing flange 2 extending .aroiind the arms and rear portion "of"-tiie yoke. Upon the bottom side of. the lower arm *3. are ribs 4 extending at right angles to the flange 2, and between pairs of which a wear shoe B is intended to be seated. 'lThewe'ai" shoe B has on its upper surface a plurality of transversely extending webs 5, each of which has a space or recess 6 adapted to fit over the flange The bottom face 7 of the wear shoe B is preferably made smooth and Specification of Le tters Patent.

flat so that it will slide upon the supporting device U with the least possible friction.

When the wear shoe B has been. placed in position between the supporting device and the yoke with the weight of the yoke and its parts upon it, the flange '2 and the cooperating webs 5 prevent relative lateral movement of the yoke and. shoe, while the ribs 4 which cooperate with the end webs 5 prevent relative longitudinal movement of the parts.

In Figs. l and 51 have shown a modified form in which only one tie plate C and one wear shoe B are employed for supporting the yoke A.

. It is obvious that various modifications may be made in the construction of the shoe which I have described and shown herein, without departing from my invention.

What I claim is:

1. A coupler yoke having, in combination therewith, a wearing shoe adapted for insertion between the yoke and a supporting device, said yoke having a flange on its under side, said shoe being movable relatively to the supporting device and having a recess in its upper face adapted to fit about said flange, tlre flange and recess comprising means to prevent relative lateral movement between the yoke. and shoe, and

means on the yoke for preventing relative dongttudinal movement between the yoke and "shoe.

2. A coupler yoke in combination with a yoke supporting member and a wearing.

shoe, the coupler yoke and the yoke supporting member being movable relatively to each other, the wearing shoe being interposed between the other two members to prevent wear on the yoke and being adapted to be movable with the yoke upon said supporting member, the yoke and the wearing shoe having laterally and longitudinally extending ribs cooperating with each other to prevent relative movement; w 5 i 3. A wearing shoe for coupler yokes comprising a plate having at reccssmm its upper face. a yoke having a flange adapted to flt in said recess, the said recess and flange preventing relative lateral movement of theparts, and stops on the yoke having hearings on the plate to prevent relative longitudinal movement of the parts. 4. A coupler yoke having on its under side a longitudinally extending flange, ti=ans- 5 verse ribs also arranged on the l nden side of the yoke, said flange and ribs being adapted to cooperate with recesses in a Wear ing shoe and to prevent relative lateral and longitudinal movement therebetween.
